To (:55 whom it concern:

Be it known tiat I, HARRY 0 Perish. e. citizen of the United States. residing at Wapelio, in the county of Louisa and State of Iowa, have invented certain new and use ful iiiiproreineiits in Glass- Cutting Toois, of which the following is a specification reference being had therein to the accompanying drawing.

This invention relates to glass cutting devices and has for its object the production of a simple and eiiicient mechanism whereby the glass may be correctly measured and marked and out according to the desired iiieasureiueiit.

Another object of this invention is the production of a simple device whereby a. sheet of glass may be cut with a straight eclge so as to insure that the glass will provided ith parallel edges.

TTith these and other objects in View, this invention consists of certain iiorel construc- Lions combinations and arrangements parts. as will he hereinafter fully described and cisiinicti.

iii the drawing:i igure 1 is a. perspective view of the cutting (lei/ice. showing the same in operation. Fig. 2 is a central loi gitucliiial section thereof. Fig. 3 is a (la aii perspective of the sliding heed.

7 i is an enlarged section through the track for the slit ing heed, showing the mum in which the heatiis carried herein. F 43 is an enlurged section through the outer end ot the graduated biacie. showing the manner of securirio same in a posit-ion at right angies e oi? the hitie. F152 6 is a *iiisrerse section throu h the inchcutter.

erring to the ch'awi will 1 (i t the base 0:. the cut ee. upon one edge with I track-way oritleti with a. ceribrace for the rear of the graduated blade 8 which is pirotall mounted upon the body of the heed 5. A threaded into the body of the head 5 as clearly iihistrateci in Fig. i and is adapted to connect the graduated blade 8 with the head The rear end; of the blade 8 extends over the suostarr .liy semicircular or are-shaped web portion 7 and a thumb screw 10 passes through the blade ancl through the web portion 7 for holding the blade 8 at right angles to the inner edge of the head 5.

A graduated scale 11 is carried near the outer end of the board 1 adjacent the outer end of the track-way 2- anti against this scale 11 is adapted; to shut the plate 12 which is to be out.

A cutting frame or member 13 is liciahiy mounted utoori olu ie 8 and. is rovideci with central opening 1 through hieh the graduated hl tie 8 masses.

w L binding screw is carried by the outer one. of the member 13 ans is adopted to clamp the menih oositiori upon the use 13 is provided Ere.

v. i a.

\' 9 against t ire heat may he *ey the therethe outer entl of s upper face and. is

-e cut g .L 1 e cutting the blade 8 in the desired manner and ad- 7 justing the indicating or cutting member 13 upon the desired point along the graduated blade 8.

By reference to Figs. 1 and 3 of the drawings, it will be seen that as the web portion 7 of the head 5 is flat and semi-circular, by detaching the blade 8, said web can be used as a guide for cutting circles and semi-circles. It will also be clear, that by releasing screw 9, and using screw 10 as a pivot, the blade 8 can be swung to angular positions, to permit angular cutting.

Having thus described the invention, what is claimed as new, is

A device of the class described comprising a base, said base provided with a longitudinally extending dove-tailed groove, a head slidably mounted within said groove, said head provided with an arc-web formed thereon, a graduated scale pivotally secured to said head, means passing through said head for binding said dove-tailed'tonguein engagement with said dove-tailed groove, said web provided with an aperture formed intermediate its ends at a point one-half the distance between said ends, and a removable pin carried by said graduated gage, said pin adapted to fit in said aperture formed in said web for holding said gage at right angles to said head.

In testimony whereof I hereunto aflix .my signature in presence of two witnesses.
